2017 Acadia Limited - NYC Metro - MF & resid for 36/39mo 10k/yr lease please

The title says all. Thanks for the help.

PS. A little bit of background.

The dealer quoted the following which I think is a terrible deal.

Rebate: 4,900
Residual 55%
39mo 10k/yr
Costco price: 49,408
Including footing 1,070 to terminate current lease.

Thanks,
David
